CPU load trigger on Windows

[scout]

Hello,

I'm monitoring Windows OS CPU load with perf_counter item (i.e. perf_counter[\Processor(_Total)\% Processor Time]). I would like to get trigger of this item if CPU load is more than 70% after 5 min.

Could you please help me how I need to set trigger for this situation like that?

Thank you.

Alex

Don't use the perf counters. Just use the built in item

key: system.cpu.util[,,avg1]
type of information: numeric float
units: %

trigger:
{server1:system.cpu.util[,,avg1].avg(300)}>70

But then you are getting CPU load calculated in Linux way but not in the Windows way.
I'd like to count CPU utilization like Windows task manager.

Don't use the perf counters. Just use the built in item

key: system.cpu.util[,,avg1]
type of information: numeric float
units: %

trigger:
{server1:system.cpu.util[,,avg1].avg(300)}>70

You are using two different terms for one thing. CPU Load is not CPU utilization. Your above perf counter is for CPU utilization. CPU Load is the number of processes waiting to be executed by the processor(s). 2 different animals.

The trigger you want to use for that perf counter, applied at the Template level would be this:

{Template OS Windows:perf_counter[\Processor(_Total)\% Processor Time].avg(300)}>70

Thank you

I already set up this trigger in my Windows template.

Btw, have you got disk IO item for Windows OS?

Is it perf_counter[\LogicalDisk(C\Disk Transfers/Sec] for disk C:?

Thanks in advance

I don't believe there is any single Windows item that will effectively give you disk IO stats on Windows. You will have to use several items and interpret them as an overall picture. Disk read/write, queue length, disk transfers, disk total time, disk idle time, file read/write - are just some that can be used to help give that picture.

Just as a note, I'm pretty certain the cpu.util does get the CPU utilisation in a windows way - as in % Processor Time.

I created an Item and a Trigger as described above. Do I need to do anything else to get this working? I created a graph using this item and it says 'no data'. The item and the trigger have green check marks next to them. Here's what I have so far, am I missing a step? Thank you, i'm new to this.

On the graph you are seeing "No data"?

Chances are you are looking at a time period before the item was implemented. make sure you have the slider bar above the graph all the way to the right so you are looking at current time.

To be sure you are getting data, go to Monitoring --> Latest data and check there.

Yup, on the graph it says no data. I also checked under monitoring --> latest data and while the item shows up, its grayed out and the last value is 0 and the change is just a '-'.

Do I have to do anything else to get this to work? I created the item and the trigger. Do I have to do anything to each client or add something somewhere else in zabbix? I remember seeing somewhere that for perf-counters you needed to edit something in each computer's Zabbix agent configuration file?
